Studio throwing error when changing any Project Properties

Support
#1

Hi,

In the latest version of Studio 6.9.5, which I upgraded to today, seems to throw and error every time I try to click Ok/Apply to any changes I make to the Project Properties. The error thrown from Studio is below.

Is anyone else having this issue?

Hi,
Which version have you updated from?
Studio Browser- or SE- edition?
Which OS do you use?

#4

Hi @iskandarov

I’m on OSX and I think I was on Studio 6.9.4. I’m on the electron based standalone edition.

I’ve tried both new and old projects and get the same issue.

I tried reinstalling Studio from scratch but that didn’t help.

#5

Hi,
Could you please provide studio.log file with described error stacktrace?
Or just the stacktrace of the java.lang.NullPointerException from the bottom of the error message.

#6

@gaslov

Here is the log file you wanted

studio.log (19.3 KB)

#7

Thanks,

Do you use any custom app components in the projects that fail with exception?

#8

Hi @gaslov

Nothing that weird. It currently builds and runs fine I just can’t do anything with the project properties. Here is my build file.

build.gradle (11.2 KB)

#9

Thanks again, build.gradle file was very helpful.

We have found the problem, it will be fixed in the next maintenance Studio release. Here is the issue.

There is a workaround: put ‘declarativecontrollers’ app component dependency before ‘helpsystem’ app component dependency in your build.gradle file.

#10

Hi @gaslov

Many thanks for looking in to this. The workaround has got me going. :grin:

Thanks again for the great support.
